Twitter reaches 11% of online Americans

Online microblogging services like Twitter, a popular social media tool for many media companies and television networks, are used by 11% of online Americans, according to a research report conducted by Pew Internet & American Life Project in December and released today. That’s up from 9% of online Americans using the service in November.

Back in May, Pew reported online microblogging usage at about 6% of online Americans.

Twitter users skew young, with one in five online Americans in the 18-to-24 demo using Twitter. But Pew also said the median age of a Twitter user is 31, compared to 27 for MySpace, 26 for Facebook and 40 for LinkedIn.
